Spontaneous germ cell death is very important for the removal of germ cells and control of the quantity and quality of sperm. But excessive germ cell death will lead to diminish spermatogenic function and decrease the quality and quantity of sperm. Excessive germ cell death triggered by various regulatory stimuli, including deprivation of gonadotropins and intratesticular testosterone or by estradiol treatment in rats via apoptosis.

生精细胞凋亡是哺乳动物精子发生过程中的一个显著特点，其生理性凋亡对于去除受损的生精细胞，控制细胞数量和保证精子的质量具有重要意义，但生精细胞的过度凋亡可引起生精功能低下，使精子的数量和质量降低。
